Atmospheric CO2 Records from Sites in the NOAA/CMDL Continuous Monitoring Network (1973-1992) in CDIAC Online Trends

The Air Resources Laboratory of the National Oceanic and Atmospheric Administration (NOAA) established four baseline monitoring stations in the mid-1970's to conduct continuous measurements of atmospheric mixing ratios. The stations are operated by NOAA's Climate Monitoring and Diagnostics laboratory (CMDL) at: Point Barrow, Alaska; Cape Matatula, American Samoa; Mauna Loa, Hawaii; and South Pole, Antarctica. Data provided by NOAA/CMDL include: Point Barrow, Alaska (1973-1998) Mauna Loa, Hawaii (1974-1998) Cape Matatula, American Samoa (1976-1996) South Pole, Antarctica (1975-1998) For more information see: "http://cdiac.esd.ornl.gov/trends/co2/nocm.htm" These data are also available from: "ftp://ftp.cmdl.noaa.gov/ccg/co2/in-situ/"
